PURPOSE:To ensure the safe and accurate transmission of the important information via a public communication circuit, by using an interface device which contains a cipher code reading function and a collating function for personal identification codes to the public communication circuit. CONSTITUTION:A terminal interface device with an answer function to call of public communication circuit is provided with a card reader 13 which reads the cipher codes recorded on a magnetic card or an IC card, a keyboard part 11 for input the cipher codes, a central processor 8, a MODEM 4, a network controller 2, etc. The processor 8 possesses the cipher codes which cannot be decoded from outside in a production stage of them in the form of the codes proper to the interface device and sends the cipher codes read with collation through the reader 13 and the part 11 to a host computer via a public circuit. The host computer specifies and confirms the card user and an individual interface device and controls the progress of an application program. |
